Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an egg transillumination inspection device used to identify defects such as blood spots, flesh spots, stains, and cracks in egg shells during the egg selection process.

[Prior Art] Systems for sorting articles and separating defective articles from a large number of articles conveyed on a conveyor are already known. One such system is disclosed in U.S. Pat. No. 4,164,291, "Classification Apparatus,"
This is a device whose purpose is to sort out undesirable objects such as stones from the harvested potatoes. The patented device provides a matrix or set of orthogonal coils for receiving electrical signals sent from a selector member. The orthogonal coils are arranged to define the arrangement of each position and are arranged in a matrix below the conveyor carrying the potatoes to be processed. A selector member or wand is provided for manual operation by an operator whose job it is to visually inspect the material on the conveyor. The selector member is rod-shaped, configured to be held in the hand of an operator, and includes a piezoelectric transducer that emits a burst of high frequency electromagnetic signals. The selector member or wand is activated when the operator comes into contact with an object that has been selected for exclusion.

The system disclosed in U.S. Pat. No. 4,164,291 is
It involves a large number of parts, especially in the formation of the matrix of coils used therein. Furthermore, this system only identifies the location of items, but does not have the ability to determine specific physical properties of items that are considered undesirable or defective.

Furthermore, the aforementioned patent indicates that it is suitable for use in the transillumination of eggs; in such a system, the coils form a grid within the inspection area that is required for transillumination. It seems almost certain that radiation will be interfered with, at least to some extent. Generally speaking, an egg transillumination device consists of a movable conveyor containing a plurality of spool bars arranged in an array and spaced apart from each other, which conveys the eggs over a high-intensity light source to detect blood spots. To visually detect various defects that may occur, such as flesh spots, dirt stains, and cracks in eggshells. Such an egg transillumination inspection device may be used alone or in combination with sorting to classify and sort eggs according to their physical properties, including weight.

[Problems to be Solved by the Invention] In the egg fluoroscopic inspection apparatus as described above, there is a limit to the operating speed of the machine, which in turn imposes a limit on the maximum operating speed of the entire automated egg processing system. In order to increase the efficiency of egg processing systems, the speed at which defective eggs can be inspected and identified by egg transillumination equipment must be increased; this requires fast and short response times. However, there is a need for an egg transmission inspection device that can identify and select defective eggs with high accuracy. Detecting defective eggs is of the utmost importance, as if overlooked, eggs that do not meet government standards will be packaged. Therefore, egg fluoroscopic inspection is slow enough to allow for accurate and complete defect detection as the eggs are transported through the egg fluoroscopic inspection machine, and yet at a speed that is slow enough to allow for accurate and complete defect detection as the eggs are transported through the egg fluoroscopy machine. It must be carried out at a high speed that does not limit the maximum operating speed.

A first object of the present invention is to provide an egg transmission inspection device in which the position of a defective egg contained in a plurality of eggs can be accurately and easily encoded as position information.

A second object of the present invention is to provide an egg transmission inspection device that can accurately and easily encode the position of a defective egg contained in a plurality of eggs and the type of at least one defect as position information and identification information. Our goal is to provide the following.

[Means for Solving the Problems] According to the present invention, the first object is an egg transmission inspection device for detecting defective eggs contained in a plurality of eggs, which comprises: a conveying means for conveying eggs in a horizontally arranged state and having an inspection range in which the conveyed eggs are subjected to a transmissive inspection; a light irradiation means for irradiating the eggs with high-intensity light upward; and a light irradiation means disposed above the inspection range and extending substantially vertically, the lower end of which is arranged above the inspection range, and has a lower end that is located above the inspection range. a rod-shaped indicating means for indicating the position of the defective eggs that should come into contact with the defective eggs contained therein; The upper end of the indicating means is supported so as to be swingable around one axis and around a second axis perpendicular to the first axis, and to be able to reciprocate along the longitudinal axis of the indicating means. a contact detection means disposed on the indicating means and detecting contact of the lower end portion with the defective egg; and a contact detection means disposed on the support means and arranged on the first shaft. and position detection means for detecting a first swing angle of the indicating means about the axis and a second swing angle of the indicating means about the second axis, respectively. achieved by.

According to the present invention, the second object is an egg transmission inspection device for detecting defective eggs contained in a plurality of eggs, the device comprising: transporting the plurality of eggs in a horizontally arranged state; a conveying means having an inspection range in which the eggs to be conveyed are inspected through light transmission; a light irradiation means disposed above the inspection range, extending substantially vertically, and having a lower end directed toward the defective eggs included in the eggs irradiated with the light; a rod-shaped indicating means for indicating the position of the defective egg to be brought into contact; support means for supporting the upper end of the indicating means so as to be swingable around a second axis perpendicular to the first axis and reciprocally movable along the longitudinal axis of the indicating means; a contact detection means disposed on the support means for detecting contact of the lower end portion with the defective egg; and a contact detection means disposed on the support means for detecting contact of the lower end portion with the defective egg; position detecting means for detecting a second swing angle of the indicating means around the second axis; a second identification signal generating means for generating an identification signal representing at least one type of defect, such as a blood spot, a flesh spot, a dirt, or a crack in the eggshell, of the defective egg that is brought into contact with the lower end portion; This is achieved by an egg transillumination device.

[Function] According to the first egg transmission inspection device of the present invention, the upper end of the rod-shaped indicating means disposed above the inspection range in which the eggs transported by the transportation means are transmitted through the transmission inspection is connected to the support means. so that the conveying means can swing freely around a first axis perpendicular to the conveying direction and around a second axis perpendicular to the first axis, and can freely reciprocate along the longitudinal axis direction of the indicating means. Because it is supported, the indicating means is oscillated and reciprocated, and a defect is observed by transillumination inspection within the inspection range.
It is possible to bring the lower end of the indicating means into contact with a defective egg located at any position within the inspection range, and since it has contact detection means and position detecting means, the lower end of the indicating means can be brought into contact with a defective egg at any position within the inspection range. The contact is detected by the contact detection means, and in this case, the position detection means determines a first swing angle of the indicating means about the first axis and a second swing angle of the indicating means about the second axis. Each swinging angle can be detected, so that when the lower end of the indicator comes into contact with a defective egg located at an arbitrary position within the inspection range, the position of the defective egg can be accurately and easily determined by the first swinging angle. The position information can be encoded as position information based on the angle and the second swing angle.

According to the second egg transmission inspection device of the present invention, in addition to the configuration of the first egg transmission inspection device of the present invention, when contact is detected by the contact detection means, the lower end of the indicating means Since the indicating means is provided with identification signal generating means for generating an identification signal representative of the type of at least one defect in the defective egg that is brought into contact with the defective egg, the same operator who causes the indicating means to swing and reciprocate Therefore, when the lower end of the indicating means comes into contact with a defective egg at any position within the inspection range by the operator's hand, the location of the defective egg can be determined. While it can be accurately and easily coded as arbitrary information by the first swing angle and the second swing angle, at least one defect type of this defective egg can be detected by the same operator operating the indicating means. It can be accurately and easily encoded as hand-entered identification information.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

, which still includes a second axis 27 . This shaft 27
is connected to the pointing means 13 by a frame member 28 as a rectangular third frame fixedly attached to the shaft 27. The shaft 27 is rotatably mounted on the frame 26 in a direction parallel to the transport direction 16. The frame member 28 has a through hole having a diameter slightly larger than the diameter of the indicating means 13, through which the indicating means 13 is slidably passed, that is, freely reciprocated. The indicating means 13 has a flange 3 disposed at its uppermost end.
0, and this flange 30 is attached to the frame 2
8 and frames 23 and 26 indicating means 1
3 rests against one end of a coiled spring 31 arranged on the pointing means 13 between the flange 30 and the frame 28 for movably supporting the flange 30 . Due to this arrangement, the indicating means 13 can be moved in two mutually perpendicular directions 1, parallel and perpendicular to the conveying direction 16.

It is now possible to enter and exit a state of contact. The support means that supports the upper end of the pointing means 13 in this way is composed of frames 23, 26 and 28, shafts 25 and 27, support beams 24, and springs 31.

Next, reference is made to FIGS. 4 to 7. The supporting means constructed as described above is adapted to direct the indicating means 1 to the defective eggshell on the spool bar 12 within the inspection range.
3 includes a position detecting means for detecting the position of the egg when the lower end 17 of the egg comes into contact with the egg. In the illustrated embodiment of the invention, this position sensing means is provided by shafts 2 mounted on frames 23, 26.
5, 27, a plurality of meshing gears 34, 35
It consists of a first potentiometer 32 and a second potentiometer 33 connected by. The potentiometer 32 is fixed to the frame 23 together with the gear 34 and is connected to the shaft 2.
Detecting the first swing angle around 5, potentiometer 33
is fixed to the frame 26 together with the gear 35, and detects a second swing angle around the shaft 27. The position detecting means generates a first signal representing at least one position in order to encode the position of the defective egg as position information based on the first swing angle and the second swing angle.

As shown in the enlarged detailed views of FIGS. 5 to 7, the contact detection means for detecting the contact of the lower end portion 17 with the egg includes a contact detection switch 36 disposed within the lower end portion 17. including. The switch 36 is located at the lower end 1
It consists of a piston 37 that is slidably disposed inside the cylinder constituted by the piston 3.
Reference numeral 7 denotes an elongated portion 38 extending airtight from an opening 39 provided in the lower end portion 17 for contacting the eggshell.
have. A pneumatic supply source (not shown) as a first supply means is connected by a tubular conduit 40 to the first pneumatic switch 41 and to the interior space of the indicating means 13 . A first opening 42 is provided in the wall of the circumferential side of the lower end 17 adjacent to the piston 37 at the lower end 17 so that when the piston 37 is in its lowest position within the indicating means 13 the opening 42
2 is open to allow air supplied through conduit 40 to escape therefrom. When the elongated portion 38 is pushed upward inside the indicating means 13 in contact with the egg, the opening 42 is closed by the piston 37 and air cannot escape therefrom, thus increasing the air pressure inside the indicating means 13. to start the air switch 41. In this way, the contact detection means includes the piston 37 and its elongated portion 38.
A switch 36, an opening 42, and a first
supply means and an air switch 41.

In this embodiment, the device 10 is further configured to code, as identification information, the type of defect found in the egg being abutted by the indicating means 13, substantially simultaneously with the generation of the first signal. It has identification information generating means for generating a second signal representing . In the illustrated embodiment of the invention, the identification information generating means includes second hand-operated air switches 43 and 44, with air switch 43
and 44 are connected at one end to a pneumatic supply device as a second supply means by tubular conduits 45 and 46 as communication means, and at the other end to a pneumatic supply device as a second supply means.
It is connected to second openings 47 and 48 provided in the. Conduits 45 and 46 extend through the interior of indicating means 13, as shown in FIGS. 5-7, and are connected directly to openings 47 and 48, respectively, for direct communication with the atmosphere. These openings 47 and 4
8 is located just above the eyelash of the opening 42,
Openings 47 and 48 can be closed by placing a finger over them.

In operation, the eggs 11 are carried on the spool bar 12 below the indicating means 13 and above the device 10. While the eggs are being carried through the inspection area over which the indicating means 13 can move, the eggs are visually inspected by the operator for defects such as blood spots, flesh spots, dirt stains, cracks in the shell, etc. be inspected. When a defective egg is discovered by the operator, the lower end 17 is first swung to a position above the defective egg and then downwardly along the longitudinal axis.
The defective egg is moved towards the egg until it abuts the elongated portion 38. At the same time, the operator presses one or both of openings 47 and 48 with a finger, or alternatively leaves both open. As can be easily seen, one of the openings 47 and 48 is closed by pressing with one finger of the operator (see FIG. 7).

Optionally, both openings 47 and 48 can also be closed or left open by the operator; in this way four different combinations are provided for differentiating between different defect types. It will be done.

The indicating means 13 is moved downward and the elongated portion 3
8 comes into contact with a defective egg and the piston 37 slides upwards, the opening 42 is closed and the pressurized air entering the indicating means 13 cannot escape therefrom. Air pressure will thus build up in the indicating means 13 and in the conduit 40 connected to the switch 41, thereby activating the switch 41. This switch 41, which may be an air-operated switch connected to a separate electrical switch connected in series with the potentiometers 32 and 33, determines the position of the lower end 17 within the test range and thus on the spool bar 12. The position detection means is commanded to generate an analog electrical signal as a first signal representative of the location of the defective egg. At the same time, when either one or both openings 47 and 48 are opened or both are closed by the operator, switches 43 and 44 are activated or not activated individually or simultaneously; A second method that distinguishes the type of defect in the defective eggs found by the operator.
An electrical signal may or may not be generated.

For example, if opening 48 were to be closed by the operator, air supplied through conduit 45 would no longer be able to escape through opening 48 and would create air pressure within conduit 45, thereby causing switch 43 is started. A switch 43 connected to the voltage source thus generates an electrical signal distinguishing the first defect type. Similarly, if aperture 47 were to be closed, switch 44 would be activated, which would generate another electrical signal indicating another defect type. Either one of these signals may be a digital signal representing the switch opening/closing conditions. If neither aperture is occluded, the absence of an electrical signal would itself indicate another type of defect. The instruction means 13 is connected to the frame 2 via a spring 31.
Since it is mounted on the spool bar 12, after it comes into contact with a defective egg by the operator, it moves away from the egg on the spool bar 12 and returns to its original position. If the piston 37 does not close the opening 42 and the operator releases his fingers blocking the openings 47 and 48, the switches 41, 43 and 44 will not be activated and the indicating means 13 will indicate the position of another defective egg. It is returned to a ready state to be used for verification.

Refer now to FIGS. 8 and 9. The electrical signal generated to represent the location of the defective egg on the spool bar 12 is generated by a potentiometer 32 and arc
Contains one electrical signal representing tanA/H. In the above formula, H represents the vertical height of the axis 25 passing through the center of the egg placed on the spool bar 12, and A represents the vertical position of the indicating means 13 at right angles to the spool bar 12. a first position 49 which the lower end 17 assumes when the indicator means 13 is placed in contact with a defective egg on the spool bar, e.g. a point 50 in FIG.
represents the horizontal distance measured along the conveying direction 16 (direction of arrow 15 in FIG. 2) between One more
two electrical signals are generated by potentiometer 33.
arc tanB/H, where H again represents the vertical height of the axis 25 passing through the center of the egg 11 on the spool bar 12, and B represents the direction perpendicular to the conveying direction 16 (in FIG. Point 5 in the direction of arrow 14)
0 and the third point 66.
As shown in FIG. 8, the difference between the angles formed when the lower end 17 is placed directly on the spool bar 12 defines the boundaries of where the eggs are located on the conveyor. determined.

The signals generated by the potentiometers 32 and 33 and the switches 41, 43 and 44 may be used to operate an egg sorting device, in which case the transillumination device 10 is used in conjunction with the egg sorting device, e.g. No. 4,164,291, used to separate defective eggs at specific locations in an egg sorting device. These signals are sent to a microprocessor and compared with numerical values stored in a table index in memory giving the location of each angle associated with the various vertically tilted positions of the indicating means 13 with respect to the spool bar conveyor. Depending on the results, an egg sorter can be operated to separate defective eggs from others. For example, when switch 41 is activated by elongated portion 38 abutting a defective egg, the electrical signals generated by potentiometers 31 and 33 will be
The various angles that the indicating means 13 makes with respect to its vertical position in the longitudinal and lateral directions 14, 15 are compared with voltages stored in memory representing the position of the defective egg on the spool bar. However, such a system is merely a preferred example; other systems exist that accomplish selection using such signals, which are well known in the art, but will not be discussed in detail here.
Details regarding the operation of a transillumination device as part of an egg processing system are described in the aforementioned co-pending US patent application Ser. No. 394,162, entitled "Egg Processing System."

Referring now to FIG. 10, an alternative embodiment of the indicating means 13 is shown. In this embodiment, the arrow indicates downstream, the indicating means 13 is slidably mounted within the bush 51, and said bush is swingably mounted on the extractor shaft 52 so that the indicating means 13 is It can move in a direction parallel to direction 16. Similarly, another extractor shaft (not shown), which is arranged transversely with respect to the extractor shaft 52, supports the bush 51, so that the indicating means 13 is
It can be guided perpendicularly to 6. The lower end 17 of the indicating means 13 includes a handle member 53 and switch buttons 54 and 55 are arranged. Switch buttons 54 and 55 constitute a second electrical switch (not shown) which generates an electrical signal when the switch buttons are pressed. Elongated portion 38, like push buttons 54 and 55, is connected to a first electrical switch which generates an electrical signal when eggshell 11 on spool bar 12 is abutted. Bush 51 also includes pins 56 extending outwardly from its surface. An oval yoke 57 is placed over the pin. The yoke is connected to a rod 58 which is slidably mounted within bushes 59, 60 such that when the indicating means 13 is pivoted about the extractor shaft 52, the rod 58 also moves. A magnetic tape recording head 61 is also attached to the rod 58,
A pair of pulleys 63 and 64 engage a magnetic tape band 62 which is driven past the recording head. A playback head 65 also engages the tape band at the end of the tape band opposite pointing device 13. Recording head 61, reproducing head 6
5. Tape band 62 is connected to spool bar 1
2 and has a number of tape recording strips corresponding to the number of columns of eggs to be conveyed through the transillumination apparatus 10. A selection switch (not shown) is connected to the indicating means 13 and is actuated by a transverse movement of the indicating means 13 with respect to the conveying direction 16 to position the egg abutted by the indicating means 13. Select the recording band of the tape band that records the column of the spool bar conveyor 12.

During operation, the instruction means 13 uses the transmission inspection device 1
The lower end 17 of the indicating means 13 is moved by the operator 0 so that it is placed over the defective egg shell on the spool bar 12. Once the indicating means 13 is placed on a defective egg, the operator then presses the indicating means until the extension 38 of the indicating means abuts the eggshell and is forced inwardly, activating the electrical switch connected thereto. is moved in the longitudinal direction toward the egg. Actuation of the first electrical switch causes the recording head to record an electromagnetic signal on the tape band 62 indicating the longitudinal position 15 of the lower end 17 of the indicating means 13. At the same time, the operator presses both or some pushbuttons 54 and 55 (or selectively presses neither button).
The indicating means indicates the type of defect found in the egg being abutted. The horizontal displacement of the yoke 57 caused by the movement of the indicating means 13
is a function of the angle formed between the vertical position of and the position where the lower end 17 of the indicating means 13 is placed at a distance X along the conveyance direction 16, and is expressed by the formula arc tanX/H.
In the formula, H is the height of the extractor axis 52 measured from the plane of the egg on the spool bar. In other words, the horizontal displacement of the yoke is directly proportional to the displacement of the lower end 17 of the indicating means 13. A selection switch connected to the indicating means 13 selects the appropriate channel for recording the signal generated by the switch connected to the extension 38.
